Its just a stronger alloy of aluminum. Strong enough that it can be thinner so a scandium frame of comparable strength will be lighter and a bit more forgiving than an identical frame made from a more pedestrian aluminum.
One of my favorite road bikes I've ever swung a leg over is a Merckx Team SC, full scandium frame. super light and responsive, and way more comforatble than your average aluminum frame. Are they all this way? Not sure, this is the only one I've ridden, but they all seem pretty light anyway. Look at the Rocky Mountain TSc, 3" travel frame, weighing 5.1lbs frame and shock.
Stan is a light guy but this year he has abandoned his FS to exclusively ride a Bandito and hasn't complained about a rough ride yet. That's from a 53 year old with an FRM super stiff carbon fork up front. I'd look like a circus freak on his bike so I've never tried it, but it must be good.
I rode a Caballero for around 7 months. I like the ride and the scandium is laterally stiff. The cockpit is too short is the only reason for me selling mine. I've not known anyone to break one. I'm guessing Reflux has never owned or broken one.
To all ya hata's out there. True, I've never owned a scandium frame and all of the info is second hand from ROAD frames. But, I know three people off the top of my hear who have cracked scandium road frames in less than one year. This was between 2 and 3 years ago, so maybe there've been some improvements, but I would still stay away.
actually, it's not aluminum. It's element number 21 on the periodic table. They may alloy it with aluminum in bicycle tubing, I'm not sure, but it is not auminum.

the quality of the build could have as much to do with the cracking as the material itself. I know a 260 clydsedale who has been on a scandium hardtail for over 2 years now, with out a single problem.
Anything superlight will not be superdurable. Scandium tubing as sold for bicycles is an aluminum alloy. The prime component of the tubing is aluminum. Just like steel bikes are cromium molybdenum or manganese molybdenum, and 3/2.5 or 6/4titanium is aluminum and vanadium added to the mix. I have personaly cracked and seen others crack prestige steel frames, a couple Klien aluminum frames a couple of older Lightspeed titanium mountainbikes, any frame can fail if its ridden hard, has a flaw or is stressed beyand what it was designed for.
